iPhone 5s iOS 9.3.4 Update: Impressions & Performance

1 / 9

We’ve spent about two weeks or so with the iPhone 5s iOS 9.3.4 update and the aging former flagship is performing quite well in key areas like battery life, connectiity, and speed. Before we get to performance, we want to touch on the installation.

It shouldn’t take you more than a few minutes to download and install if you’re coming from iOS 9.3.3. If you’re coming from an older update, it’ll take a little bit longer. We didn’t run into any installation problems with the upgrade.

As for the iPhone 5s iOS 9.3.4 update’s performance, we haven’t noticed any abnormal battery drain during regular use and we don’t expect that to change in the weeks ahead. If you are seeing issues, there’s a good chance it’s not iOS 9.3.4 causing the problem.

We haven’t experienced any issues with Wi-Fi, AT&T’s 4G/LTE networks or Bluetooth. We’ve successfully paired the iPhone 5s, and its new update, with several different routers, ISPs, and Bluetooth devices. We haven’t noticed anything out of the ordinary.

The iPhone 5s in our possession is still fast with the iOS 9.3.4 update on board. There’s still a little bit of sluggishness when using Control Center (this was also an issue for us on iOS 9.3.3), and the keyboard occasionally stalls, but that’s the only noticeable UI lag we’ve seen.
